Headlamp for a motor vehicle

Abstract

A headlamp for a motor vehicle is provided, the headlamp including a plurality of first light sources for a high beam, emitting light during operation of the headlamp, and a plurality of second light sources for a low beam, emitting light during operation of the headlamp. The headlamp also includes a first light guide having a plurality of light entry surfaces for the light emitted from the first light sources and a first light exit surface, as well as a second light guide having a plurality of light entry surfaces for the light emitted from the second light sources and a second light exit surface. An optical component is also provided, which may be a monolithic optical component, and which comprises both the first and the second light guide.

I claim: 
     
       1. A headlamp for a motor vehicle, the headlamp comprising:
 a plurality of first light sources for a high beam, emitting light during operation of the headlamp; 
 a plurality of second light sources for a low beam, emitting light during operation of the headlamp; 
 a first light guide having a plurality of light entry surfaces for the light emitted from the first light sources and a first light exit surface; 
 a second light guide having a plurality of light entry surfaces for the light emitted from the second light sources and a second light exit surface; 
 an optical component which comprises both the first and the second light guide; 
 wherein the plurality of light entry surfaces on the first light guide are positioned and located on a light entry plane; 
 wherein the plurality of light entry surfaces on the second light guide are positioned and located on the light entry plane; and 
 wherein the light entry plane is oriented perpendicular to the light emitted from the plurality of first light sources and the plurality of second light sources. 
 
     
     
       2. The headlamp according to  claim 1 , wherein the optical component has a light exit surface formed by the light exit surfaces of the first and second light guides. 
     
     
       3. The headlamp according  claim 1 , wherein the light exit surfaces of the first and second light guides are adjacent to and/or merge into one another. 
     
     
       4. The headlamp according  claim 1 , wherein the headlamp comprises means for generating a horizontal cut-off line. 
     
     
       5. The headlamp according  claim 1 , wherein the first light exit surface is inclined to the second light exit surface. 
     
     
       6. The headlamp according  claim 1 , wherein the optical component serves as a primary optics. 
     
     
       7. The headlamp according  claim 1 , wherein the optical component has at least one collimating lens. 
     
     
       8. The headlamp according  claim 1 , wherein the light exit surface of the optical component has a structuring. 
     
     
       9. The headlamp according  claim 1 , wherein the light entry surfaces are formed by the ends of light guide elements projecting from the component. 
     
     
       10. The headlamp according  claim 1 , wherein the first and/or the second light sources can be controlled individually or in individual groups. 
     
     
       11. The headlamp according  claim 1 , wherein the light sources are light-emitting diodes. 
     
     
       12. The headlamp according  claim 1 , wherein the headlamp has a secondary optics through which the light emerging from the light exit surfaces of the first and/or the second light guide passes during operation of the headlamp. 
     
     
       13. The headlamp according to  claim 12 , wherein the secondary optics has a collimating lens which is adapted to the at least one collimating lens of the optical component serving as a primary optics. 
     
     
       14. The headlamp according to  claim 12 , wherein the secondary optics have a structuring which is arranged in particular on the collimating lens.
